> Problem: kswapd, kreclaimd, kupdated push load average high during simple
> tar. Response of system drops such that even keystroke echos are
> noticeably delayed.
>
> Specifics:
>
> Machine- 4 processor 700Mhz Dell with 4G Ram and 6G swap space running
> stock Redhat 7.2 distribution. All disks are SCSI using ext2.
>
> Command- from a remote machine this command is executed to the Linux
> machine "tar cBf - . | rsh linux "(tar xBpf -)".
>
> Manifestion of problem- As this command continues on a freshly booted
> Linux machine the free memory reported by 'top' slowly goes to a low
> number. When it bottoms out, the processes 'kswapd', 'kreclaimd', and
> 'kupdated' begin to run pushing the load average above 4 at times.
> Responsiveness of machine drops dramatically with even keystroke echos
> delayed for seconds.
